Returns the smallest convex Polygon that contains all the points in the Geometry.
[Visual Basic]
Function ConvexHull() As Geometry
Returns the minimum-area convex polygon containing this Geometry's points.
This obviously applies only to Geometrys which contain 3 or more points; the results for degenerate cases are specified as follows:
| Number of Points in argument Geometry | Geometry class of result |
|---|---|
| 0 | Empty GeometryCollection |
| 1 | Point |
| 2 | LineString |
| 3 or more | Polygon |
